efficient two-step synthesis of O-(2,4-dinitrophenyl)hydroxylamine is described along with a comparison of its aminating efficiency with O-mesitylenesulfonylhydroxylamine (MSH). It was used in an expedient N-amination/benzoylation procedure involving various substituted pyridines, leading to polysubstituted N-benzoyliminopyridinium ylides, and the scope of its amination power was studied.
描述了一种有效的两步合成O-(2,4-二硝基苯基)羟胺的方法,并比较了其与O-次甲基亚磺酰基羟胺(MSH)的胺化效率。它被用于方便的N-氨基化/苯甲酰化过程,涉及各种取代的吡啶,导致多取代的N-苯并亚氨基吡啶基吡啶化,并研究了其胺化能力的范围。
